Possible Microsoft Durango Hardware Specs Leaked

A site has released what it says is a look at the technical specifications behind Microsoft's Xbox 360 successor, which is going by the code name Durango. If they're to be believed, the next generation will provide more than just an incremental upgrade.
Site vgleaks.com has posted the specs, including the system diagram pictured above.
Some of the reported highlights include 8 GBs of DDR3 RAM, a Blu-ray drive, and hardware support for the next iteration of Kinect.
Here's the complete list. As always, take it all with a grain of salt.
CPU:
- x64 Architecture
- 8 CPU cores running at 1.6 gigahertz (GHz)
- each CPU thread has its own 32 KB L1 instruction cache and 32 KB L1 data cache
- each module of four CPU cores has a 2 MB L2 cache resulting in a total of 4 MB of L2 cache
- each core has one fully independent hardware thread with no shared execution resources
- each hardware thread can issue two instructions per clock
GPU:
- custom D3D11.1 class 800-MHz graphics processor
- 12 shader cores providing a total of 768 threads
- each thread can perform one scalar multiplication and addition operation (MADD) per clock cycle
- at peak performance, the GPU can effectively issue 1.2 trillion floating-point operations per second
- High-fidelity Natural User Interface (NUI) sensor is always present
Storage and Memory:
- 8 gigabyte (GB) of RAM DDR3 (68 GB/s)
- 32 MB of fast embedded SRAM (ESRAM) (102 GB/s)
- from the GPU’s perspective the bandwidths of system memory and ESRAM are parallel providing combined peak bandwidth of 170 GB/sec.
- Hard drive is always present
- 50 GB 6x Blu-ray Disc drive
Networking:
- Gigabit Ethernet
- Wi-Fi and Wi-Fi Direct
Hardware Accelerators:
- Move engines
- Image, video, and audio codecs
- Kinect multichannel echo cancellation (MEC) hardware
- Cryptography engines for encryption and decryption, and hashing

Looks like they more interested in pushing all this sh*t like Kinect with all that move engines and etc than in creating a true next gen console.

Multi threading
Most of that looks plausible. If accurate, then it would basically have to be AMD Jaguar cores together with either a VLIW4 (Radeon HD 6900 series or Trinity integrated graphics) or GCN GPU--and probably the latter, as GCN has been out for a while.
ESDRAM would probably be the whole on-package memory via a silicon interposer that is supposed to be a big deal for feeding integrated graphics. The idea is that you put the very heavily accessed framebuffer and depth buffer there so that you don't need to use system memory for them.
I would raise an eyebrow at 68 GB/s of memory bandwidth done via DDR3 memory, though. Yeah, you do need that sort of bandwidth to feed a GPU that will be about on par with a Radeon HD 7770, so it makes sense that they'd want it. How they'd get it is a different matter, though. What's that going to be, quad channel 2133 MHz DDR3?
Looks like a good step up IMO, You can't expect a console to have the most updated hardware btw, it would cost too much and no one would buy it.
But this system would set them up easily for another 6-7 years in my opinion, it's just such a leap from the 360.

If you mention rose tinted glasses, you better be referring to Mitch Hedberg.
The GPU is probably 12 GCN CUs. For comparison, a Radeon HD 7770 is 10 GCN CUs clocked at 1 GHz. That should be in the ballpark of 2-3 times the performance of the GeForce GT 440 that you cite.
There is more to CPU performance than just clock speeds. Different architectures can have wildly different performance levels even at the same clock speed.
More cores clocked lower tend to give you more performance than fewer cores clocked higher. Jaguar cores will be capable of having separate cores running completely independent code, so you don't have the threading problems that the PS3's Cell processor had. That's enough that actually pushing all eight cores shouldn't be very hard to do if your game needs that kind of CPU power.
Games, perhaps. Games are pretty easy to scale to nearly as many cores as you want, if you actually need a ton of CPU performance. (Well, within reason. Scaling to 100 cores could be rough.) Threading most of the CPU work that a game engine does is a completely straightforward producer-consumer queue.
I suppose that it depends some on what you mean by "top of the line". You could make a console in a typical console form factor that puts out 300 W and cool it no problem. Remember that Microsoft can make the console whatever shape they want, as it's easily a high enough volume product to justify custom engineering.
But there's a difference between "can" and "should". 300 W in a typical console form factor is likely to be very loud. It would also be much higher end hardware, and thus very expensive.
